Bechtel Plant Machinery has received a $303 million contract from the U.S. Navy to supply nuclear propulsion components.

The Navy uses nuclear propulsion capabilities to power a variety of its vessels, including submarines and aircraft carriers. The solution allows ships to operate by drawing power from a small nuclear power plant installed on the vessel.

The U.S. Department of Defense did not provide an estimated date of completion for the project, but did disclose the work will be performed in Monroeville, Penn., and Schenectady, N.Y.

Bechtel received $205 million in Fiscal 2016 shipbuilding and Fiscal 2017 procurement funding at the time of the award. The contract was not procured competitively. The Naval Sea Systems Command in Washington, D.C., is listed as the contracting activity.
